EMBROIDERY-MACHINE.

To all whom t concern.'

Be it. known that'I, WILLIAM COHEN, a citizen of the United States, and a resident of Bayonne, in the county of Hudson and State of New Jersey, have invented a new and Improved .Embroidery-Machine, ofl which the following is a full, clear, and

Sired depth or length of loop may be provided by pro er adjustment of certain parts.

-Another o' ject of the invention-.is to provide la hand embroidery machine with one or a plurality of needles, and one or a num'- ber of sources of supply for the needles so that a plurality of rows o embroidery loops may be produced at one time if desired.

-A further object of the invention is 'to provide a hand operated embroidery machine in which the' machine automatically feeds itself forward regardless of the adjustment of the needles as to the length of loop provided. v

In the accompanying drawing:

Figure 1 is a perspective view of an embroidery machine disclosing an embodiment of the invention.

Fig. 2 is a longitudinal vertical section through the structure shown in Fig. 1.

Fig. 3 is a sectional view similar to Fig.

2, but showing the needle and associate parts in their different positions.

l, Fig. 4 is a longitudinal vertical sectional Aview through the lower part of the structure shown in Fig. l, same being-on an enlar ed scale showing the needle as it is about e withdrawn from the cloth prepared to to make another stitch or loop'.

Fig.,5 is a perspective view of a readyV adjustment gripping jaw 'embodying certain features of the invention. p Fig. '6 is a perspective view of a pivotally mounted gripping jaw for needles embodying certain features of the invention.

In the present invention it is aimed to provide aready adjustment ofthe lengthof thel loop as well'as provide onel "or a `large )Patented May 1918.

number of needles, rand to provide each needle with the same kind of thread, or silk, or dierent kinds'and diiierent colors.

Referring to the accompanying drawing by numerals, 1 indicates a' piece of cloth of any desired kind on which it is desired to provide some embroidery using a design of any desired kind.- As shown -in Figs. 2, 3 and 4 the various loops 2 are arranged on the side of the cloth which is opposite to that engaged by the machine. From this it will'be seen that the embroidery is worked from whatis termed the wrong side. The

foot 3 is caused, to contact with the cloth' ofthe parts, and to assist in causing the device to operate so as to move in a straight line automatically. Frame 4 has rigidly secured thereto, or formed integral therewith, means for supporting spools 5'and 6 of thread, said. means being in the nature of a shelf 7 havingl upstanding pins 8 arranged thereon on which the spools freely rotate. In they, drawing two spools are shown and twowneedlesuQ and 1U, but it will `be evident .that one or more than two could be used without departing from the spirit ofthe invention. The needlesf9 and l0 lit .into suitable sockets in the jaws 11 and 12, jaw-'1l having a threaded aperture 13 for receiving the clamping screw 1'4 which. eX-

tends through asuitable slot 15 in the frame 4'and through an aperture 16 in jaw 12 as well vas an aperture 17 in the reciprocating sleeve 18. Sleeve 18 as well. as the frame 4 is cut away somewhat on one face at the lower part so as to accommodate the feeding spring 19, as well asv to accommodate the jaws 11 and 12. A pivotally; supporting pin 2O is carried by the lower part of the -sleeve 18, said pin extending through an aperture 2l 'in the jaw 12 so as to pivotally support said jaw. It will be noted `that the `jaw 12 isrounded at 22 so as to allow a movement from the position shown in Fig.

,provided in the upper part of jaw 12 for secured at 25 -to the sleeve 18 whereby the y spring as well as jaws 11 and 12 reciprocate with said sleeve. This spring and the pivotal mounting of the jaw 12 acts in connection with the needles and foot 3 to feed the device forward after each stitch. When the device is ready for use it is positioned as shown in Figs. 1 and,2 and the needles move downwardly, or pass through the cloth 1, as shown in Fig. 8, and in doing so on both the downward and upward movement act to force the parts-to the position shown in Fig. et, so that as soon as the needles are completely withdrawn the spring 24 will act to throw the needles forwardly from the position shown in Fig.. 4lto that shown in Figs. l and 2, whereby when they are forced downwardly again they will be in advance of the previous stitch. In order to cause a proper up and down movement of the needles they are connected by pin 20 as heretofore described tothe sleeve 18 which slides in the frame 1, said sleeve extending above said frame for an ap;` Mqciable distance.

fr band 26 surrounc the sleeve 18 near lthe top, said band conforama' to 'die shape of the sleeve and having a catcn 27 pivotally connected therewith, said catch being normally held in position shown in Fig. 2 by a spring 28. Catch 27 is provided with a locking member 29 adapted to lit into any of the apertures 30 in sleeve 18 whereby the up and down movement of the sleeve is limited as the band 26 will strike against the upper part of frame 4: and the screw` 1e will strike against frame l at the upper end of slot 15. When it is desired to lengthen the stitches or loops 2 the band 26 is moved upwardly toward the knob 31 and when it is desired to shorten the loops2 catch 27 is disengaged and the band 26 moved downwardly toward the frame and the catch rengaged so as' to allow a greater or less reciprocatory movement of the sleeve 18 and needles 9 and 10 and associate parts.y In order to provide the proper feed from the spools 5 and 6 the spring 19 is moved downwardly a short distance before sleeve 18 begins to move, said spring having an eye 32 for each spool provided.

It will be observed from Fig. 2 that the spring 19 is rigidly secured to a sliding bar 33 positioned in the sleeve 18, said bar carrying at the upperv end the knob 31 which is grasped by one hand `while the frame 4f is grasped by the opposite hand during the operation. When the device is being grasped in the manner stated foot 3 is placed against the cloth 1 and the needles are caused tov move up and down by movement cf knob 31 and associate parts. The hand which grasps the frame e will steer or guide the incenso device so as to follow any 'desired pattern provided on the cloth.

When placing the threads from spools 5 and 6 in position for operation they are preferably threaded through the eyes as shown in Fig. 1 and then brought down over the bent portion 34 of spring 19 in lorder to provide a proper tension on the threads without the use of complicated tension means. lt is, however, evident that the threads could be passed through the eyes in the opposite direction if preferred. 1n order to allow this part of the device to operate and pull the threads from the spools before the dcwnwardmovement of the needles a pin 35 is connected with the sliding bar 83 and extends 'through the slot 36 formed in sleeve. 18 whereby the up and down independent movement of the bar 331 is limited and consequently the independent movement of the spring 19 is limited.
